VALVE DEVICE.

Specication of Letters Patent.

Patented Dec. 21, '1909.

Application filed July 20, 1908. Serial No. 444,429.

To all whom it may concern:

Be it known that I, JOHN MILLER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Valve Devices, ofwhiclithe following is a specification.

One object of the invention is. to provide improved means for opening avalve which is normally held to its seat by means of a spring, and tothis end a rod is arranged at right angles to the valve stem and aneccentric is arranged on the rod in position to engage the valve stem.

Another object of the invention is to provide means for permittingexpansion and contraction of the various arts of the valve devicewithout injury, an( to this end the valve casing is supported by rodsextending from a slab or other primary support so that the valve casingand the valve-operating rod move independently of said support.

The invention consists in the features of novelty that are hereinafterdescribed with reference to the accompanying drawings, which are made apart hereof, and in which:

Figure 1 is a vertical central section of a valve device embodying theinvention. Fig. 2 is an elevation thereof on a smaller scale. Fig. 3 isa horizontal section, full size, on the line 3 3, Fig. l, with theeccentric in plan.

The valve casing, 1, has an inlet port, 2, and an outlet port, 3. Theinlet port is surrounded by a valve seat, 4, to which is adapted avalve, 5, seating with the tlow of the water and held normally seated,by a coiled spring 6. The stem of the valve is guided by suitable meansand its inner end projects into the chamber of the casing, 1, inposition to be engaged by an eccentric 7, carried by a valve rod, 8,having a handle, 9, for turning it. The pitch of the eccentric is suchthat by turning it through less than a half-circle (sa 1550) in onedirection or the other, it willyfully open or` fully close the valve asthe case may be. will remain in whatever intermediate position it isstopped, and hold the valve in corresponding position-wholly or partlyopen. The movement of the eccentric in one dircction is .limited by thecontact of shoulders on lts pitch is also such that itlugs 10 and 10acariiedby the leccentric and casing, respectively, and in the otherdirection by shoulders 11 and 1l, the former of which is formed directlyon the eccentric, while the latter is formed by a lug carried by thecasing.

The valve rod is without threads. At its lower end it is supported andguided by a spider 12, in the outlet port 3, and at the upper side ofthe casing it passes through a stutlingv box 13. The screw cap or plugwhich cai-ries the stutling box is provided on its under side with asleeve 13a which surrounds the rod and projects downward far enough toact as ,a stop for engaging the eccentric and preventing its upwardmovementfai' enough to disengage it from the valve stem. Above thestulling box the valve rod passes through a sleeve, 14, secured to aslab, 15, or other support. The upper end of the sleeve is provided witha flange, 16, which bears upon the top surface of the slab and isthreaded on its exterior to receive a nut, 17, a plate, 1S, beinginterposed between tlie nut and the under side of the slab. With thisarrangement, *when the nut is turned up, for which purpose it isprovided, at 19, with a nonciicular portion for receiving a wrench, theplate will be firmly clamped against the underside of the slab orsupport and the sleeve will be firmly secured in place. in its openingthrough the slab. The plate has on its under side two tapped bosses, 20,and into these are screwed the threaded upper ends of two supportingrods, 21, lock nuts, being turned onto the rods and into engagement withthe bosses. The lower portions of the rods pass freely throughperforated lugs, on opposite sides of the casing, and below these lugsadjusting nuts, 24, are turned onto the rods for supporting the casingat the desired position with relation to the slab or support. Theadvantage of this construction and arrangement of the parts is that theyare allowed perfect freedom oi movement relatively to cach other andare, therefdre, not liable to break or bind.

The improv `d valve device' may be used for various puiposes but isespecially adapt cd for hydrotherapeutic. baths in which they tureswhich are sometimes not only suddenbut also both sudden and extreme. T A

The entire valve device is subgect to bodily up and down movement due tothe expansion and contraction of the Waste pipe, 24:,

with which the outlet port 3 communicates,

' the Water limited to this and this expansion and contraction is soconsiderable that it frequently breaks the slab when the valve device isrigidly attached thereto. It rj'for this reason that the valve is freelymovable on the rods 2l, and .the valve rod 8 is capable of movingendwise through the sleeve 14.

The sudden changes in the temperature of passing throughthe valve casingproduces sudden relative changesv in the sizes, proportions, or relativepositions of the several parts, due to their` unequai eX- pansion orcontraction, and eiitreme changes due to these causes produce aconsiderable disturbance oralteration in the relations of the partsfrequently resulting in their breakage, distortion, or other damage orinjury whichl will prevent or materially interfere with the properoperation of.y the valve device.

It is, of course, known that an eccentric is one form of cam and Idesire to have it understood that the present invention is notparticular form. 'On the contrary a cam of any form that will accomplishthe desired result is Within the scope of the invention. f
